Intelligence Quotient (IQ) Score
An Intelligence Quotient (IQ) Score is a intelligence score from an IQ test.
- Context:
- It can (typically) measure Cognitive Performance through standardized testing.
- It can (typically) indicate Intelligence Level through normalized scoring.
- It can (typically) evaluate Mental Capability through comparative assessment.
- It can (typically) quantify Intellectual Function through statistical distribution.
- It can (typically) represent Cognitive Ability through population comparison.
- ...
- It can (often) predict Educational Achievement through performance correlation.
- It can (often) indicate Job Performance Potential through capability assessment.
- It can (often) reflect Learning Capacity through cognitive measurement.
- It can (often) inform Special Needs Assessment through capability analysis.
- ...
- It can range from being a Low IQ Score to being a Normal-Range IQ Score to being a High IQ Score, depending on its standard deviation from the median.
- It can range from being a Raw IQ Score to being a Normalized IQ Score, depending on its calculation method.
- It can range from being a Subtest Score to being a Full Scale IQ Score, depending on its test coverage.
- ...
- It can integrate with Educational Planning for academic placement.
- It can support Professional Assessment for job placement.
- It can inform Development Planning through capability evaluation.
- ...
- Examples:
- Standard IQ Range Scores, such as:
- Below Average Scores, such as:
- Extremely Low Score of 25 for severe limitation.
- Borderline Score of 50 for significant limitation.
- Average Range Scores, such as:
- Median Score of 100 for typical performance.
- Above Average Scores, such as:
- Superior Score of 150 for exceptional ability.
- Highly Superior Score of 250 for rare capability.
- Below Average Scores, such as:
- Specific Domain Scores, such as:
- ...
- Standard IQ Range Scores, such as:
- Counter-Examples:
- G Factor, which is a theoretical construct rather than a specific score.
- EIQ Score, which measures emotional intelligence rather than cognitive intelligence.
- SAT Score, which indicates academic achievement rather than general intelligence.
- SIQ Score, which assesses social intelligence rather than cognitive capacity.

- An intelligence quotient, or IQ, is a score derived from one of several standardized tests designed to assess intelligence. The abbreviation "IQ" comes from the German term Intelligenz-Quotient, originally coined by psychologist William Stern. When current IQ tests are developed, the median raw score of the norming sample is defined as IQ 100 and scores each standard deviation (SD) up or down are defined as 15 IQ points greater or less, although this was not always so historically. By this definition, approximately 95 percent of the population scores an IQ between 70 and 130, which is within two standard deviations of the median.
IQ scores have been shown to be associated with such factors as morbidity and mortality, parental social status, and, to a substantial degree, biological parental IQ. While the heritability of IQ has been investigated for nearly a century, there is still debate about the significance of heritability estimates and the mechanisms of inheritance.
IQ scores are used as predictors of educational achievement, special needs, job performance and income. They are also used to study IQ distributions in populations and the correlations between IQ and other variables. Raw scores on IQ tests for many populations have been rising at an average rate that scales to three IQ points per decade since the early 20th century, a phenomenon called the Flynn effect. Investigation of differing patterns of increases in IQ battery subtest scores informs current research on human intelligence.
